ALONZO HITCHCOCK, OF NEW YORK, N. Y.

IMPROVEMENT IN MODE OF HANGINGv DOORS.

Specification forming part of Letters Patent No. 41.006, (lated December 22, 1863; antedated December 13, 1863.

To @ZZ whom it may concern:

Be it known that I, ALoNzo HITCHCOCK, ot New York, in the county and State of New York, have invented a new and useful Improvement in Hanging Doors 5 and I do hereby declare that the following is a full. clear,

and exact description of the same, referencev being had to the accompanying drawing, making a part of this specification, and to the letters of reference marked thereon.

In sliding doors hitherto the extent of the support has been restricted to the width of the doorway, which is usually so much less than its height that the tendency to cant or tilt and. jam diagonally has been productive of great inconvenience.

The object of my invention is to extend the Width of the support in sucli a manner that the application ofthe force necessary to open or close the door will cause it to move iii the required direction without this objectionable diagonal tendency and it consists in hanging the door on a tube or bar which projects beyond one or both of its edges, and slides or travels on another tixed bar or tube in such a manner that the weight ofthe door prepoiiderates over the opening or closing face and retains it in its proper vertical position.

To enable others skilled in the arts to which it appertains to make and use my invention, t I will proceed to describe its construction and operation with reference to the drawing,which represents the end trame ot'aii ordinary streetsame is extended or not.

railway car with a door hung and applied according to my said invention.

The frame-work a is made in the usual maiiner. The door b is hung by the clamps c upon the tube d, which extends beyond the edge to surfaces.

which the handle is affixed, and is supported on the rod e, that passes through its interior and is secured to the frame by means of screwnuts at its ends. The rode may also be made tubular for the purpose ot combining lightness with stiffness and strength, and it may be supported in the vicinity ofthe middle ot its length by the suspensionrod f, which passes through a slot in the upper part of the tube d between the clamps. The door should be made somewhat wider than the opening ofthe doorway, so that when it is entirely closed the rear edge is retained within the casing, to prevent swinging.

Having thus described the manner in which I prefer to apply my invention, I would here state that it may be modified and arranged iii a variety of ways without departing from its nature as herein set forth. llhe door, instead of being suspended at its upper end, may be supported at the bottom on a base similarly extended, or it may be hung at both the bot tom and the top, and-it may travel on rollers or wheels, instead of merely sliding on plane In double doors` the points of sup port may be placed slightly' out ot' center, so that the sliding tubes or bases may pass and lap each other when the doors are closed.

Iclaim as my invention and desire to secure by Letters Patent- 1. Hanging a sliding door on an extended support, substantially in the manner described.

2. Suspending a door on a tube, whether the A. HITCHCOCK. Witnesses:
